`5 Claims.

Fig. 41s a perspective view of the closed con-` tainer.

The blank, say of liber or paper stock in sheet form, is shown as embodying sections I, 2, 3, 4, and adhesive strip 5 having therebetween scor- .ing 6. 'Ihese sections may be assembled to form a tube with the strip 5 in abutting relation on the inner portion of the section I remote from :i the section 2. There is thus eilected the square tube forming of this body for the container.

'Ihis container additionally has terminal extensions from this body portion for closure. As

herein shown, scorings 1 from the body portions i' I, 3, form a joint for minor bottom flap portions 8. offsetting blank thickness relatively to the scorings 1 and from the` sides 2, 4, are scorings 9 for major inner panel section I0 from the body section 4 and major outer panel section II from ill) the body section 2.

'I'his panel section I0 is of greater extent from the score line 9 than the length of the score line 1. This addition is according to the wall thickness of the container so that as the ap I0 is folded over the minor flaps 8, free terminus I2 of the flap I0 may abut against the inner side` of the root or base of the ap I I adjacent the scoring 9. This outer major flap II does not overhang from the base of the container or project beyond the iiap I0, for the reason that this 50 II, there are uncut portions I5 from the cut I3 and from cut I6.

Additionally, the strip 5 does not have its terminus I1 extend directly to the score line 6 but has oset I8 approximately 45 directly con- {15 necting to the iiap III on the side of the score line 9 away from the body portion 4. These portions I8, I5, are effective in the folding-in of the bottom closure of the container in maintaining a crowding oi' the stock of the container at the corners and thereby in such regions being effective for tight sealing of the container at this bottom, say prior to leak-proof coatingH thereof.

'I'his container, in addition to this bottom closure, has a tight sealed closure at the top. 10

This additional closure comprises r rallelogram portions I9, 20, from the sides 2, s; triangular portions 2I from the sides I, 3 of the body portion. These triangular portions have minor right angle triangular portions 22 which, with 15 the triangular portions 2I complete rectangular portions in series about the tube with the intermediate parallelogram portions I9, 20. 'I'he triangular portions 22 have trapezoidal portions 23 therefrom, one at thebase of each of the triangles 22 -as away from the body portion. 'Ihe strip 5 in its extent beyond the body portion 4 embodies sections 24, 25, along the extent of the parallelogram portion and additional portion 26 which has its side 21 tapering outward similar to the tapering outward of diagonal side 23 of the respective trapezoids 23. Accordingly, when the strip 5 is in assembly position with the body portion or side I, this portion 21 may, insofar as its extent, register iiush with the inclined free edge 28 of the trapezoid 23 with which it is assembled.

From the parallelogram portions I9, 20, there are minor parallelogram portions 29 which, together with the trapezoid portions 23, are assembled into a four-ply rib. In fact, there are lve plies to the extent of the strip portion 25. Into this rib there is a tuck-in tongue from the side 20, 29. This tongue has at its base, score line 30. The tongue adjacent this score line 30 has straight portions 3I giving the tongue a width at least for two plies of the thickness of the container Wall.

From this full width portion tapered sides 32 extend to the free end of this tuck-in tongue 33. This full width base portion 3l of the tongue insures tight fitting of the tongue at its base or the upper terminus portion of the rib closure. From the side 2 and parallelogram portions I9,

20 therefrom, there is score line 34 about which tongue 33 is outside tongue 35 having straight portions 3B of full width of the score line 34. This full Width portion 36 is of an extent over the four plies of the rib as now including the tuck-in tongue 33. It is accordingly, of greater extent than the4 straight or full width portion Il of the tuck-in tongue II. From this full width base portion Il, tongue 3B has tapered portions ll. tongue 33 tucked in, there may be a snug or mm holding of the rib for this outside fold-over tongue I8. 'I'he corners are thus, in each instance, compact, with ,the stock for a maximum of resistance against liquid leakage.

l. A container including side walls and an end closure comprising folded extensions of the side walls, said extensions having adjacent edges interconnected and terminating, respectively, in

panel sections disposed in parallel adjacent. ,'planes, said terminal panel sections together forming a central transverse rib, one oi the outer panel sections of the rib having a tongue integral therewith, portion of which closely overlies the rib and portion of which is parallel to and outside o f the other outer panel section. the rib overlying portion of such tongue being co-extensive in length with the rib ando! .a width substantially to cover said rib. and the remainder closure comprising folded extensions of the side tapering toward its free end.

2. 'A container including side walls closure comprising folded extensions oi the side walls,y said extensions having adjacent edges interconnected and terminating. respectively, in panel sections disposed -in parallel adjacent planes, said terminal panel sections `together' forming a central transverse rib, one of the outer panel sectionsf the rib having a tongue integral therewith, portion oi' which closely overlies ai portion of the rib and the remainder .oi' which is parallel to and inside oi the other outer panel section, the rib overlying portion ot suchtongue being co-extensive in length with the rib and of a width substantially to cover lsaid rib, and the remainder tapering toward its free end.

These are of advantage. in that with the 3. A container including side walls and an end' closure comprising folded extensions of the side walls, said extensions having adjacent edges interconnected and terminating, respectively, in panel sections disposed in parallel adjacent 5 planes, said terminal panel sections together forming a central transverse rib, bothoi' the outer panel sections of the rib having tongues integral therewith, one of said tongues having a portion completely overlying the rib and the 10 second having a portion which overlies the -rib save for the paneltowhichthenrsttongueis connected, the said `overlying portions of the tongues being in close contact, one outside of the other, and each being co-extensive in length 15 with the rib and of a width substantially to cover said rib, and the remaining portion of said second tongue being tapered toward its free end and being disposed inside of and parallel to the panel to which the nrst tongue is connected. gg 4. The combination set forth in claim 3 in which the. two outer panel sections are equal in length, measured longitudinally of lthe rib, and co-extensive in length with the rib.
